Pemmin's Aura + Blossom Dryad + Teferi's Isle

Pemmin's Aura

Blossom Dryad

Teferi's Isle

How it works

1. Activate Teferi's Isle by tapping it, adding .
2. Activate Blossom Dryad by tapping it, untapping Teferi's Isle.
3. Activate Pemmin's Aura's first ability by paying , untapping Blossom Dryad.
4. Repeat any number of times.

This clever loop turns Blossom Dryad into an efficient mana-generating engine by wrapping it in Pemmin's Aura, which uses a single unit of blue mana to untap the Dryad repeatedly. To fuel this untapping, you tap Teferi's Isle for a pair of blue mana, which Blossom Dryad then untaps so the cycle can continue. Because Teferi's Isle provides a net gain of two blue mana while Pemmin's Aura only requires one blue mana to untap the Dryad, you are left with an infinite surplus of blue mana and endlessly untappable lands.
